A computer-implemented method, computer program product, and computing system for implementing multi-temporal tables in a database is described. One or more databases are utilized, wherein the one or more databases implement a first temporal table that includes a first and a second time domain. The one or more databases are enabled to implement a second temporal table that includes at least a third time domain, wherein the second temporal table is associated with the first temporal table.

System and method for implementing multi-temporal database functionality

Embodiments of the invention provide data management solutions that go beyond the traditional warehousing system to support advanced analytics. Furthermore, embodiments of the invention relate to systems and methods for extracting data from an existing data warehouse, storing the extracted data in a reusable (intermediate) form using data parallel and compute parallel techniques over cloud, query processing over the data with/without compute parallel techniques, and providing querying using high level querying languages.

System and method for building a cloud aware massive data analytics solution background

Methods and arrangements for accommodating and synthesizing data for seeking broad-based solutions to complex problems. Logical models with respect to infrastructure in a first location are created. System-level models are created with respect to the logical models, and simulations are performed on the system-level models to verify expected behavior. Feedback is employed from the performed simulations to forecast changes in the system-level models.

Systems and methods for exploring and utilizing solutions to cyber-physical issues in a sandbox

Methods and arrangements for accommodating a query, directing the query to datasets, creating partitions and partitioning the datasets, and returning a response to the query, the response being structured in accordance with the created partitions.

Systems and methods for massive structured data management over cloud aware distributed file system

In the context of cloud computing, effective methods and arrangements for storing and tracking provenance. In accordance with at least one embodiment, a distributed file system is advantageously employed to store large amounts of provenance data. File creation involves the creation both of output files and reduce logs.

Systems and methods for tracking and reporting provenance of data used in a massively distributed analytics cloud

Techniques for identifying one or more inconsistencies between an unstructured document and a back-end fact-base are provided. The techniques include automatically parsing a query document and comparing the document with a back-end fact-base comprising facts relevant to the document, identifying one or more inconsistencies between information mentioned in the document and the facts stored in the back-end fact-base, and providing a response to the query document, wherein the response additionally includes the one or more identified inconsistencies.

Detecting factual inconsistencies between a document and a fact-base

A plurality of sources are registered. A plurality of schemas are constructed, based on the plurality of sources. A desired output is obtained as a conjunctive query. A list of potential connections between at least selected ones of the sources is provided. A plurality of join plans are developed, based on the connections.

Method for assembly of personalized enterprise information integrators over conjunctive queries

System and computer program product for assembly of personalized enterprise information integrators over conjunctive queries

Methods, systems and computer products perform cost estimate to determine an efficient approach to answer a query according to one of several unified query plans. One unified query plan involves querying an unstructured database, referencing a unified index, and probing a structured database based on matches discovered in the unified index. The results of the unstructured database query are used to lookup entries in a unified index associated with the structured database. Then the structured database is probed by querying only the subset of the structured database gleaned from the unstructured database query.
